GE's LM2500s to Power Japan's 16DDH Destroyer

Posted on May 4, 2005

GE Transportation’s marine gas turbine business announced it will supply Ishikawajima-Harima Heavy Industries, Co. Ltd. (IHI) with four GE LM2500 aeroderivative gas turbines. The engines will power the first of a new class of Japan Maritime Self-Defense Force’s (JMSDF) helicopter-carrying destroyers.

The first vessel will be known as the 16DDH, and it is anticipated that at least one additional DDH destroyer will be built in the coming years.

The 13 500 t DDH destroyer will use two propulsion trains, each consisting of two LM2500s in a COmbined Gas turbine And Gas turbine configuration (COGAG), driving a propeller through a gearbox. The engines will each provide 18 640 kW of power.

“This is an exciting project for the JMSDF as it marks the first of these new helicopter-carrying destroyers,” said Karl Matson, general manager of GE Transportation’s marine business in Evendale, Ohio.
